IMPROVEMENT IN HVDRANTS.

Specification forming part of Letters Patent No. l52,/l6, dated July '7,1874; application filed April o, 1874.

To all whom it may concern.:

Be it known that we, JAMES D. KEEGAN and WALLING D. GREANELLE, of NewYork, in the county and State of New York, have jointly invented certainImprovements in Hydrants, of which the following is a specilication:

Our invention relates to certain improvements whereby the hydrant isrendered easily accessible without the necessity for removing the eartharound its foot, and specially relates to that class wherein the hydrantis provided with an outer case or jacket for its protection below thesurface, said case or jacket remaining permanently in the ground, andthe hydrant being bolted thereto, so as tobe readily removed whennecessary, such features being old and well known in the arts; but ourinvention consists in forming upon the enlarged or valve portion of thehydrant an annular iiange,

Awhich has its seat upon a ring rising from the top portion of the mainwater-n'iain, so that an annular space will be between the outer surfaceof the valve-chamber and the interior surface of a pipe connecting thehydrant proper with the water-main, the object being to prevent rustingof the said surfaces should they be in contact with each other, as isnow the case. j,

In the accompanying drawings, Figure 1 is a side elevation of a hydrantembodying our invention. Fig. 2 is a vertical section of the same. Fig.3 is a side elevation of the hydrant without the jacket. Fig. 4L is adetail view hereinafter particularly referred to.

The case or jacket B is connected to the water-lnain A below the surfaceof the ground by ilanges b and bolts in the usual manner, and extends uptothe surface of the ground, where the hydrant C C' is secured to it bymeans of flanges l and bolts m. It' desired, instead of having angesformed on both the jacket and the hydrant, as in Fig. 2, the flange maybe on the hydrant only, and the upper edge of the jacket may bethickened and formed with a shoulder for the reception of the portion ofthe hydrant near the ilange l,

so that the bolts may screw directly therein,

as in Fig. 4, thereby rendering the use of nuts unnecessary.

The portion C of the hydrant which is above ground is of about a sizecorresponding with that of the jacket; but the portion C', which isbelow the surface, is smaller than the inside caliber of the jacket,except at the lower end, where it is enlarged into a conical orapproximate spherical form to provide for a valve, and has a shoulder,c, formed ou its lower end for engagement with a shoulder, a, and anannular rib, a2, formed on the water-main A, as shown in Fig. 2. lu theconical or spherical enlargement is formed a val ve-seat, d, forengagement with the valve D.

Both the valve and valve-seat are ground to lit each other closely, soas to render packing unnecessary, and this is only accomplished in ourinvention bythe construction ofthe valve-chamber with respect to thecasing B. An annular space is created between the two, so that allrusting of the parts is prevented, and each is nicely supported.

rlhe shoulder upon the main, which enables us to create the space, issuchV that it necessitates a similar construction of the base of thevalve-chamber.

The Valve D is attached to a rod, e, which passes through a suitablestuffing-box above the spout f, and is provided with a handle forturning it, said handle being accessible through the lid or cover g.Immediately above the valve-scat orifices 'i are formed, for the escapeof waste-water into the jacket, which may have a waste-pipe, j,connecting with a sewer or cess-pool.

It will readily be seen that this invention may be applied to hydrantsof every description and constructed of any suitable material. A

By forming the connect-ion of the hydrant and the case at a point abovethe surface of the ground by means of the flange. Zand bolts m, thehydrant may be detached without removing the earth around the foot.

Across the lower end of the conical or' spherical lower portion of thehydrant, ex-

tends a bar provided with a perforation, or rib co2 on the Water-main7whereby is prothrough which the lower portion ofthe vaiveduced anintermediate space between the rod E passes7 and is thus prevented fromdis- Vabre-chamber and the Jacket B, as set forth.
